Question

A chemistry graduate student is given 250. mL of a 0.40M acetic acid (HCH3CO₂) solution. Acetic acid is a weak acid with K=1.8 x 10³. What mass of
KCH3CO2 should the student dissolve in the HCH3CO2 solution to turn it into a buffer with pH = 4.30?
C
You may assume that the volume of the solution doesn't change when the KCH3CO₂ is dissolved in it. Be sure your answer has a unit symbol, and round it to
2 significant digits.
